/* Danmaku Minipack - recolored glitch/horror theme (red -> site orange
   accent), Share Tech Mono -> Courier New for site-wide font consistency.
   All animation MECHANISMS (flicker, glitch shake, text scramble, waiver
   gate, audio fade-in) are unchanged - only colors/fonts/borders differ.
   Loaded after /style4.css so it can build on the shared --bg/--text/
   --accent/--muted-dim variables. */
